Okay, I've realised I don't know what a shirt is either. I always thought they were things with collars, but then people talk about collarless shirts... it's all so confusing! Go and listen to In Rainbows. Now.
How did you manage to get it on vinyl? The arrangements are so beautiful... If you like it, try the rest of OK Computer, Kid A, and Absolution by Muse. With Fitter, Happier I reckon the tone's more defeated whereas with Paint it's more resigned. Which sounds like it's the exact same thing, but with resigned you can be resigned to do something and keep on doing it, whereas with 'defeated' it seems more passive.
